What's new in terms of product integrations, is NX11 supported? It would be nice to see the compatibility matrix.
NX11 is not supported in 8.14.0. But it will be available in 8.14.1.
There are two documents you might find of interest among the other Rulestream 8.14 downloads on GTAC. First, the System Requirements document includes the compatibility matrix you are seeking. Second, the Release Notes document describes what is new in the release.
